“…Prior studies regarding radial tuberosity anatomy used microCT images while standard CT images where used for this study. Similar results between measurements on microCT and standard CT have been reported (8). As the thickness of the anterior and posterior cortex in present study are comparable to previous mentioned results, we assumed that standard CT is indeed as proficient to measure cortical thickness.…”

“…We opted for standard CT images to obtain a large measurement cohort which significantly surpasses the number required in the power analysis. Finally, the measurement of the posterior and anterior cortex at the radial tuberosity is comparable to previous microCT measurements (8). Second, given that the CT scans were taken for different indications on a non-standardized manner we manually aligned the plane of the radial tuberosity by using the sagittal and coronal planes to have standardized measurements.…”

“…There is a need to place two buttons as the anterior cortex of the radial tuberosity is markedly thinner than the posterior cortex. This has been shown in small series evaluating the cortex thickness and density at the radial tuberosity (8).…”

“…There is little known regarding the anterior cortex anatomy around the radial tuberosity, its thickness in different sections and its possible importance in assuring a good resistance to pulling out of the implants use in surgical reinsertion of the DBT. The few studies that describe the anterior cortex are small series (8).…”

The aim of this study was to measure cortex thickness and medullar canal width of the bicipital tuberosity, to evaluate the accessibility of a intramedullar fixation device and the resistance to pullout strengths of the anterior cortex. The final objective was to determine the length of tendon ingrowth size that will be expected when using this surgical technique. A total of 144 computer tomography images of the proximal radius were used. Bone thickness of the anterior and posterior cortex and medullar canal size were measured. The possible ingrowth of the tendon was measured both for an anatomical and non- anatomical reinsertion. Statistical and concordance analyses of results were performed. The average width of the medullar canal was 8,7mm proximal, 7,9mm distal and 7,7mm at the tuberosity. The average posterior and anterior cortex measured respectively 2,5mm and 2,9mm proximal, 3,2mm and 3,2mm distal and 2,8mm and 1,9mm at the radial tuberosity. The possible non-anatomical ingrowth was 7,6 mm on average and the possible anatomical ingrowth was 7,6mm on average. The radial tuberosity anatomy can accommodate the new distal biceps fixation device. The anterior cortex on which the new device relies for support has a similar thickness as the posterior cortex used in bicortical fixation devices which may suggest similar resistance to pull-out strengths. The availability for intra-osseous fixation of the tendon stump may avoids tendon gapping. The intra-osseous length for the tendon stump surpassed reported tendon slippage during mobilization and active contraction of the distal biceps tendon.
